Seven Rajya Sabha MPs from the Aam Aadmi Party—including Raghav Chadha and Harbhajan Singh—have joined the Bharatiya Janata Party, sharply reducing AAP’s strength in the Upper House to just three members.

This shift has significant legal implication: the defecting MPs may face action under the anti-defection law.

Anti-Defection Law in India: Key Provisions and Criticism

• The anti-defection law is contained in the Tenth Schedule, added by the 52nd Constitutional Amendment Act 1985 to curb political defections and ensure stability in legislatures.
• Changes Introduced by the 91st Amendment (2003)
  • The 91st Constitutional Amendment Act 2003 strengthened the law in two major ways:
    • Stricter Merger Rule - At least two-thirds of a party’s members in a House must defect together to qualify as a valid merger. If fewer members switch, they face disqualification proceeding. This replaced the earlier rule that allowed a one-third split, which had been widely misused.
    • Cap on Council of Ministers - Total number of ministers capped at 15% of the strength of Lok Sabha or State Assembly. Minimum of 12 ministers allowed in smaller states. This aimed to reduce political inducements and office-based defections.
  • Removal of the ‘Split’ Provision - The earlier provision recognising a one-third split as legitimate was removed because it enabled frequent defections. The new two-thirds rule makes switching parties more difficult and accountable.
• Flipsides of the Anti-Defection Law: Erosion of Legislative Independence
  • While the anti-defection law was designed to curb political instability and horse-trading, it has significantly restricted the autonomy of legislators.
  • Members risk disqualification even for defying the party whip, limiting their ability to represent constituency interests or independent judgment.
  • This has led to increased centralisation of power within party leadership, making elected representatives largely subordinate to party decisions rather than accountable to voters.

Disqualification Debate After AAP MPs’ Defection

• The defection of seven Rajya Sabha MPs from the Aam Aadmi Party to the Bharatiya Janata Party has triggered a legal debate under the anti-defection law.
• One view suggests that no disqualification may occur if the Rajya Sabha Chairman accepts the shift as a valid merger, since more than two-thirds of AAP’s MPs in the House have joined the BJP—an exception allowed under the Tenth Schedule.
• However, others argue that the merger provision applies to the entire political party, not just MPs in one House.
• This implies that for the exception to hold, the party leadership—potentially including Arvind Kejriwal—would also need to formally merge with the BJP.
• Without this, the MPs could still face disqualification petitions, which any member can file before the Chairman.
• Role of the Rajya Sabha Chairman
  • Until a ruling is made, the defecting MPs will officially remain AAP members, even if they functionally align with the BJP.
  • The Chairman has the authority to either:
    • Accept the move as a merger, protecting them from disqualification, or
    • Reject it and proceed with disqualification proceedings
  • The decision can subsequently be challenged in court.
• Impact on Voting and Parliamentary Dynamics
  • During the interim period, a constitutional anomaly arises: although technically AAP members, the MPs may vote with the NDA, increasing its effective strength in the Rajya Sabha.
  • AAP can still issue a party whip, and any defiance by the defecting MPs could become separate grounds for disqualification.
  • The Chairman will also decide such cases, adding another layer of uncertainty.
  • The situation highlights legal grey areas in the anti-defection framework, where the final outcome depends on the Chairman’s interpretation of the merger clause and subsequent judicial scrutiny.

Anti-Defection Law: Consequences if Two-Thirds Threshold Is Not Met

• If fewer than two-thirds of members had defected, the rebels would have been liable for disqualification under the Tenth Schedule.
• Any member could petition the Rajya Sabha Chairman to act against them for switching sides or defying the party whip.
• However, the law does not prescribe a time limit for the presiding officer’s decision, allowing delays that can let members continue in office despite being liable for disqualification.
• Judicial review is possible only after the Chairman’s ruling, creating scope for prolonged uncertainty, even though the Supreme Court of India has advised that such cases be decided within a reasonable time.
